Abstract Metal oxide arrester (MOA) plays a very important role on ensure the safe operation of power system, so regular preventive tests are essential, The accuracy of tests results are effected by several factors. For DC high voltage in field test of 1000kV MOA, influence factors and treatment methods of leakage current are analyzed; impacted of current limiting resistance on test results are comparative analyzed, method to eliminate the effect of limiting resister is provided; according to the field test situation, a better wiring method is proposed to reduce workload and raise the working efficiency.
